Why is -x cube always negative for any nonzero value of x?
The premise of your question is false: -x³ is positive if x is negative.
Why any number raise to the power 0 is always 1?
== == The fact is - any nonzero number raised to 0 is always 1. the reason is: suppose a is nonzero. Then by the quotient rule of indices, am/an = am - n Taking m = n we come up with am - m = am/am , which is 1 in view of a nonzero.
Is the sum of zero and positive number always sometimes or never zero?
Never.
If any nonzero raised to the power of zero is equal to?
It is always 1
Is the product of a nonzero rational and a irrational number irrational?
Yes, always.
What is absolute value of the opposite of a nonzero rational number?
The absolute value is always positive.
Explain Why the product of two nonzero absolute values is always a positive number?
An absolute value must be greater or equal to zero. If the absolute value is known to be nonzero then it must be greater than zero: that is, it must be positive. The product of two (or more) positive numbers must be positive.
The sum of zero and a negative integer is always sometimes or never zero?
The sum of zero and a negative integer can never be zero - it will always be negative and nonzero. Although zero is also an integer, it is neither negative nor positive and cannot be the other integer used.
Why is -x cube always negative for any nonzero value of x?
The premise of your question is false: -x³ is positive if x is negative.
Why can velocity be negative but nonzero speed is always positive?
speed is a scalar quantity with magnitude only but no direction; velocity is a vector with both magnitude (speed) AND direction, which could be positive or negative
What is always the result of dividing an integer when the divisor is nonzero?
A rational number is always the result of dividing an integer when the divisor is nonzero.
Is the sum of positive and negative integers sometimes positive yes or no?
Yes. But NOT always.
Does the difference between a positive decimal and a negative decimals can always sometimes or never be positive and why?
It is always positive, and not just for decimal numbers but for all numbers.
Is negative n always sometimes or never a positive number?
Sometimes.* If "n" is positive, "-n" is negative. * If "n" is negative, "-n" is positive. * If "n" is zero, "-n" is also zesro.
Is a nonzero integer always be a rational number?
Yes.
Which operation will always result in the value of 1 for any nonzero number?
The operation that will always have the result in value of 1 for any nonzero number is Inverse Operation of Multipication.
Why the product of nonzero rational number and a rational number is an irrational?
Actually the product of a nonzero rational number and another rational number will always be rational.The product of a nonzero rational number and an IRrational number will always be irrational. (You have to include the "nonzero" caveat because zero times an irrational number is zero, which is rational)
